The crow family Corvidae, are the largest birds of the Passeriformes. This group show themselves at the very least, to have a flexible approach to their food-finding and interaction between fellow species members, and with other animals. Some of the larger species (especially in the genus Corvus) also show levels of learned behavior of a high degree, and even insight in some examples that can be interpreted as intelligence.

There are many species in this family, but they can be divided into well-defined groups.

• The Crows, genus Corvus, including Ravens

• The Jays

• The Choughs, genus Pyrrhocorax

• The Magpies

• The Treepies

• The Nutcrackerss, genus Nucifraga

• The Ground Jays, genus Podoces

• Stresemann's Bush Crow, Zavattariornis stresemanni

• Piapiac, Ptilostomus afer

Hume's Ground Jay (Pseudopodoces humilis) has now been asigned to the Tit or Titmouse family (Paridae). See link below for latest details:
